Washing machine laundry drum

摘要

The laundry drum is configured for removing water from wet laundry at a high rotational speed and has a circulating drum cover which is bent from a thin-walled material strip to form a cylinder or flat truncated cone wherein the parallel end edges of the material strip make contact in a connecting seam, with an assembly for connecting the end sections including a first tab formed at a first end section and continuing over the general curvature of the drum cover, a second tab formed at a second end section wherein the second tab is at least one of outwardly creased about the wall thickness of the material strip and inwardly creased about the wall thickness of the material strip wherein the tabs of the end sections are fixedly connected to one another and the overlapping tabs on the inside of the drum cover are covered.

1. A washing machine laundry drum configured for removing water from wet laundry at a high rotational speed, the drum comprising:
a rotating drum shell which is formed from a thin-walled material strip to form at least one of a cylinder and a flat truncated cone with a cone angle less than or equal to about 15° in a manner wherein first and second end sections of the material strip make contact along a connecting seam, a connection along the connecting seam that connects the end sections, the connection including
a first tab formed at the first end section of the material strip, the first tab being curved such that the first tab follows a general curvature of the cylindrical or truncated cone shape of the drum shell, the first tab being a continuation of the material strip such that the first tab and the material strip follow an unstepped curved line;a second tab formed at the second end section of the material strip wherein the second tab is one of outwardly stepped an amount of about the wall thickness of the material strip and inwardly stepped an amount of about the wall thickness of the material strip; anda lifter that covers the connecting seam,wherein the tabs of the end sections overlap and are directly fixedly connected to one another where they overlap, andthe tabs are covered by the lifter on the inside of the drum shell where they overlap.
